Denseflakes, glider is T(moves at c/2), have a common sparky sort-of-high-period oscillator, have TWO spiral oscillator(one statorless), BORDERLINE EXPLOSIVE. EDIT: 14o! evolves into 4 gliders + a large SL.

You can add all B4 transitions except B4a and non-symmetric patterns don’t explode unless they gain symmetry.
Here’s one which emits what appears to be a knightship but is actually not, in B4-aDenseFlakes

EDIT:
I like this rule I found a while ago. (I lost it in my files but found it today)
It's three transitions from life, it's nonexplosive, and it has loads of 9c/20 pi-based technology, including (probably) every size of cordership starting with 2.
